Mr. Guhan is a Ph.D. student studying the gene expression profile of neutrophils from blood cancer patients. He is planning to produce neutrophils from hematopoietic stem cells rather than isolating patient blood samples. But, he has no idea how to make neutrophils from stem cells. Can you give a conceptual approach to make neutrophils from stem cells? Explain how you can convince Mr. Guhan that your idea works better? What are the distinct stages of cell differentiation that occur before reaching neutrophils? Explain at least one of the major ligands and its pathways involved in the growth cycle. What are the different ways he can confirm the cells that he produced are neutrophils?

Two 10- and 11-years old boys infected with a Respiratory syncytial virus (RSV) and consulted a physician. Their mother states that a high fever occurred during the last 24 hours. The physician observed that both had a viral illness and laboratory test positive for RSV infection, and the mother told the doctor both received a subunit vaccine against RSV a year ago. For the first son, fever disappeared the next day but not for the second son, have high fever and breathing problems even after five days. Write a detailed explanation and schematic diagram/graph for the following questions: What are the immunological reactions that might happen during the vaccination in both first and second children? Why the boys got RSV infection even after vaccination? Why fever disappears for the first why not to the second? What kind of immunological response might happen to the first and second children after infection?

A local hospital has informed a family that some of the children may have been mixed up with children from other families when they were born.

The following were the outcomes:

Father: Type O Mother: Type A

1st child: Type O 2nd child: Type A

3rd child: Type B Mom's father: Type AB
